Abstract

The invention relates to a tanning agent for dogskin and a tanning technology of the dogskin. The tanning agent comprises o-carboxybenzaldehyde, diisocyanate, urea formaldehyde resin, polyvinylpyrrolidone, dibutyl itaconate, bicarboxyethyl amine, sodium phthalate, maleic acid, di-n-butylamine,fatty aldehyde and sodium persulfate. The tanning technology comprises the steps of sequentially performing water soaking, fleshing, softening, tanning and airing on the dogskin. The tanning agent specially exerts a good tanning effect on the dogskin; the tanning on the dogskin by the tanning agent can effectively simplify procedures; dogskin leather can be obtained only by performing the water soaking, the fleshing, the softening, the tanning and the airing on the dogskin; the tanning procedure has a fat abstraction effect on the dogskin; the tanning technology is effectively simplified; the tanning efficiency is effectively improved; the production cost is effectively lowered; the prepared dogskin leather has good characteristics of softness, smoothness, wear resistance, good elasticity and the like.

Description

technical field [0001] The invention relates to a tanning agent and a tanning process thereof, in particular to a tanning agent especially suitable for dog skins and a tanning process thereof. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. [0003] The current leather tanning process is relatively complicated. For example, the Chinese invention patent with application number 201310725180.5 provides a goatskin synthetic tanning process. Meat → secondary degreasing → pickling → softening → tanning → neutralization → drying with water → regain moisture and shovel until soft. The tanning process requires multiple processes of immersion in water, degreasing, etc., the proc...
